    Carbon Intake on the Dyno

    Intake works like a champ! 377whp with the intake making 47 hp over the CSL intake.

    got proof? That's a pretty huge difference.

    Is it just the piece after the airbox to the headlight opening ?

    Q: Just the headlight scoop added 47 rear wheel hp? Hard to believe when the dyno is static with air flow solely from fans.

    Too many...or...NOT
    SneedSpeed,

    Suggestion - Avoid Teasers, the slippery slope of a runaway thread is coming.

    More of us like/demand data to support claims - Baseline, list of mods, ambient conditions, then final dyno, etc..etc...etc..

    I see you have data for other things on your website - so i'm sure you've got some to share.

    Best of Luck!!

    Maybe a small turbine wedged some place in there?

    Looks pretty awesome though, even better when there is a dyno graph.

    Saw this on FB. Also curious to see some back to back dyno plots. That is quite the increase... How is the air filtered?

    The ram air scoop really has nothing to do with the power gain. All power came from the velocity stack we build into the scoop. We have found no real power gain on just "ram air" type setups without velocity stack or other intake integration.
    The air is filtered using the stock CSL type air filter
    The air box picked up the power without ECU tuning because the original tune was rich but is now to lean to be safe. We are currently retuning the ECU now. More to come...
    The dyno is in the picture- look under the back wheels.

    Hi Chris... I'm thinking dyno sheets that show the before and after is what we're looking for.

    I am not trying to be a jerk, but even with dyno sheets what I am hearing is that the Baseline run was running bad, more air happened to make BIG gains by coincidence. Not apples to apples.

    I'll post some dynos when I get done tuning.

    Car was running pretty go when it got here, I think it turn in a 2.0x something at VIR with the tune it came in with and Tom Long driving. It was tuned at another shop and was then brought to me because the owner felt it could make more power so...
    If you change air flow on an engine you need to add fuel - more air can burn more fuel and that equals more power. Sometimes by reducing turbulence in the intake or exhaust tract you can make power by getting the air into the engine quicker and atomizing the fuel better causing a more complete burn and thus making more power because of better use of the current fuel load. This is how OEMs continue to make more power and get better MPG.

    Chris I agree with your last statement, but could you really look me in the eyes and tell me that this piece allows 47 additional rwhp? Your average reader in this section knows better.

    Do you feel the original Motorsport snorkel was restrictive?

    adding a velocity stack adds 47rwhp?

    Are you saying this adds 47 hp ON TOP of the CSL intake numbers?

    Or 47 hp when used in conjunction with the CSL intake over stock?

    I would be absolutely amazed and shocked if it added 47 horse power on top of the CSL intake gains but i am willing to be impressed.

    In for real dyno sheets/numbers...

    Before/after dynos, otherwise it's still hard to believe.

    Sounds like this proves just how tempermental alpha N tunes are, not how much better the hardware is.

    I assume you're using alpha N since all the BMW guys love it?

    Hard to believe.. because the CSL intake is VERY open indeed...

    Yes this is HP above the CSL intake.

    The CSL intake is by no means restrictive, the issue is not with restriction here its more about how the air enters the plenum. Because the hole is large and has no radius so it creates alot of turbulence and hurts air flow into the intake. Have you ever seen an intake like this on anything else? Wonder why?

    Toolean- I'll look you in the eye and tell you it works because it does. This intake isnt even for sale so why would I lie about it.

    I have NO love for Alpha N tuning but yeah thats what it has and its a pain in the ass
